st: single-line vs multiple-line -if- command

["Zurab Sajaia" <zsajaia@hotmail.com>]

Dear all,

I encountered a strange behavior -if- and/or macro inline incrementation 
operators and was wandering what's going on.

Lets consider this example:

local a=1
local b=1

if 0 local a1=`a++'

if 0 {
   local b1=`b++'
}

display `a', `b'
2 1

Although both expressions are false an therefore neither a1 nor b1 will be 
created, `a' is incremented anyways. If we say that two versions of -if- 
statement are equivalent then I'd expect exactly same outcome no matter what 
type of commands and operations (like inline macro substitution) is used. Am 
I confusing something here?

I would appreciate any thoughts about the issue,

Thanks,
Zurab
